Abstract
The utility model discloses a thermocouple supporting device. The thermocouple supporting device includes a supporting rod, fixing clips and a bow-shaped spring sheet. Two ends of the spring sheet are fixed on the supporting rod through the fixing clips; and a center portion of the spring sheet is provided with an opening for the insertion of a temperature-measuring element. The thermocouple supporting device provided by the utility model can be adopted to support the temperature-measuring element of a thermocouple so as to enable the temperature-measuring element to reliably abut against a protective jacket, thereby ensuring the accuracy in temperature measurement. The thermocouple supporting device of the utility model is especially suitable for enabling each temperature-measuring element to abut against the wall of a protective jacket when a plurality of temperature-measuring elements are installed in the small-diameter protective jacket.
Description
Technical field
The utility model relates to the thermopair technical field, is specifically related to a kind of thermopair bracing or strutting arrangement.
Background technology
Element as detected temperatures, most widely used is thermopair, current in chemical industry, many devices need to detect the temperature of a plurality of positions, and multipoint thermocouple (multipoint thermocouple is applicable to the production scene and exists thermograde not remarkable, must measure simultaneously the many places of a plurality of positions or single position and measure.Multipoint thermocouple is widely used in the devices such as large chemical fertilizer synthetic tower, storage tank) be widely used thereupon.Multipoint thermocouple in the market mainly is comprised of flame proof waterproof junction box, protective casing and temperature element.Because temperature element is free state in protective casing, can not be close to tube wall, causes the thermometric out of true.
Summary of the invention
For above-mentioned technical matters, the utility model provides a kind of thermopair bracing or strutting arrangement, supports by the temperature element of the utility model to thermopair, and temperature element and protective casing are close to reliably, improves the degree of accuracy of thermometric.
The technical scheme that realizes the utility model purpose is as follows:
The thermopair bracing or strutting arrangement comprises support stick, fixed card and is arc spring leaf that the two ends of spring leaf are fixed on the support stick by fixed card, and the middle part of spring leaf is provided with the opening that inserts for temperature element.
Fixed card is U-shaped fixed card.
Fixed card and support stick are welded and fixed.
The opening of spring leaf extends from arc summit to arch surface.
Adopted such scheme, when using the utility model, an end of temperature element is inserted in the opening of spring leaf after by this opening clamping.With the curved curved shape in the end of temperature element; the temperature element end extends to the opening outside of spring leaf and is in the top on arc summit; therefore; after bracing or strutting arrangement being inserted in the protection pipe box of thermopair; because stay pipe can occupy a part of space in the protective casing; remaining space is then distributed to spring leaf and measuring sensor; because the diameter of protective casing is less than the radial dimension of bracing or strutting arrangement maximum; after bracing or strutting arrangement is inserted in the protective casing; temperature element can form with the tube wall of protective casing and contact; tube wall imposes squeezing action power to temperature element; spring leaf is subjected to this squeezing action power generation deformation; spring leaf imposes reverse back stretch, makes the end of temperature element and the tube wall of protective casing form tight note, thus the accuracy that satisfies quick temperature measurement and improve thermometric.
Further; the opening of spring leaf extends from arc summit to arch surface; be positioned at arc place, summit owing to open an end of product; when being inserted into temperature element in the opening; the arc top, summit, position, end of temperature element be can be convenient to make, the end of temperature element and the tight note of wall of protective casing are convenient to make.
When the utility model is specially adapted in the protective casing of minor diameter branched temperature element is installed, every temperature element all is close to protecting tube wall.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is the assembly structure figure of utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the vertical view of spring leaf.
1 is support stick, and 2 is fixed card, and 3 is spring leaf, and 3a is opening, and 4 is temperature element.
Embodiment
Referring to figs. 1 through Fig. 3, thermopair bracing or strutting arrangement of the present utility model comprises support stick 1, fixed card 2 and is arc spring leaf 3.Fixed card 2 is U-shaped fixed card, and fixed card 2 is welded and fixed with support stick 1.The two ends of spring leaf 3 are fixed on the support stick by fixed card, and the middle part of spring leaf 3 is provided with the opening 3a that inserts for temperature element, and the opening of spring leaf extends from arc summit to arch surface.
When using the utility model, an end of temperature element 4 is inserted among the opening 3a of spring leaf 3 after by this opening clamping.With the curved curved shape in the end of temperature element 4; the temperature element end extends to the opening outside of spring leaf and is in the top on arc summit; therefore; after bracing or strutting arrangement being inserted in the protection pipe box of thermopair; because stay pipe can occupy a part of space in the protective casing; remaining space is then distributed to spring leaf 3 and measuring sensor 4; because the diameter of protective casing is less than the radial dimension of bracing or strutting arrangement maximum; after bracing or strutting arrangement is inserted in the protective casing; temperature element 4 can form with the tube wall of protective casing and contact; tube wall imposes squeezing action power to temperature element; spring leaf is subjected to this squeezing action power generation deformation; spring leaf imposes reverse back stretch, makes the end of temperature element and the tube wall of protective casing form tight note, thereby improves the accuracy of thermometric.
